Students today have far more opportunity than when 5% went to university. Nowhere in the world would you be able to access say 50k in unsecured loans for a 3 year course (even at 10% interest). There is no doubt that students today have a much better deal than the 5% from 40 years ago.
As for asset prices, they reflect the false market we have had for 10 years, as well as the fact that we live in one world. Apart from prices adjusting when the older demographics bite into housing supply, is it really wrong that anyone be open to competition from other human beings some of whom achieve more/less? The answer is always to get better, not unsustainable protectionism.
Minimum wage £10 per hour, £400 a week, £20000 a year. If you lived a student's lifestyle, you'd save enough within 5 years to get by, and be comfortable topping up your funds when studying. By all means take the loan as a buffer if you wish, knowing you could pay it off any time when you finish, and save a small fortune in interest. All around the world, that's how it's done. And in so doing that would-be student almost certainly learns more in useful life skills than going straight from school, spending other people's monies, some planning to never repay a gift that should be life-changing.
I would not be surprised at a much higher 'graduate tax' rate being levied in future. The lower the tax rate for graduate loans, the more other taxpayers have to pay for nothing of worth to them, or to the student.
